It is possible that on occasion you have needed to factory reset an iPhone, iPad or iPod touch, that is, an Apple product with an iOS or iPadOS operating system. Performing it from the device itself is simple, however, if you do a complete restoration you can ensure a more thorough cleaning of said device, something that you can only achieve using a computer for it. And, in this regard, It is probably easier from a Mac, but you can also do it without any problem using a Windows computer.
To do this, it is true that you will need a previous step more than if you do it directly from macOS, such as the installation of the necessary programs, but it will not be too complicated so you can achieve it without any difficulty.
So you can restore your iOS or iPadOS device from a Windows computer
ITunes download
Currently, there are a multitude of third-party programs that will allow you to perform these actions. Now, the truth is that the most recommended and the official Apple is iTunes, which apart from the characteristics related to music will also allow you to manage aspects of those devices that you decide to connect to your computer. For this very reason, you will need to download this program, taking into account that it also includes the drivers corresponding to the devices.
To download, If you have Windows 10 on your computer, you will be able to get iTunes directly from the Microsoft Store for free, but if you have an older version of the operating system, then you will have to access the Apple website to download and installation manuals for the program in question. Once the installation is done, you can continue with the steps.
Restore your device using iTunes
Firstly, connect your iPhone, iPad or iPod touch to your Windows computer through the USB cable and open iTunes. The program will automatically detect it and install the corresponding files and drivers, so you can manage your device without any problem. As soon as it is ready, in the upper left you will see an icon representing your device, with the corresponding form, and if you press it, you will access a new tab in which all the information related to it is detailed, being able to manage the contents and everything you need.
In the overview, next to the same data, you should see two buttons appear, one to update your iPhone, iPad or iPod and one to restore it. You will only have to click on the second to start the process in question.
Then It will show you the different license agreements of the iOS or iPadOS version that you must accept, and then it will start downloading the corresponding version. Said download will be made from Apple's servers in a secure way, and in the upper left you will find the download progress, represented through a small circle that will be completed as you progress. Of course, the downloads will be several gigabytes, so depending on your Internet connection it is possible that the waiting time is longer.
Once the download is done, you can see how iPhone, iPad, or iPod touch enters DFU mode and begins installation. The progress in question appears both at the top of iTunes, where the different recommendations that are being followed are indicated, as well as on the device itself, just below the brand's logo.
Finally, the device will restart if everything has gone well, and the program will show it to you by means of a warning on your computer. This restart is somewhat slower than usual, but when it finishes your device will be ready to go. Then you just have to perform its configuration, something that you can achieve both from your iPhone, iPad or iPod touch directly by following the steps that will appear on the screen, as well as from your computer with iTunes if you wish or do not have an Internet connection.
